## `tkinter.simpledialog` — Standard Tkinter input dialogs

Source code: Lib/tkinter/simpledialog.py

The `tkinter.simpledialog` module contains convenience classes and functions for creating simple modal dialogs to get a value from the user.

tkinter.simpledialog.askfloat(title, prompt, **kw)
tkinter.simpledialog.askinteger(title, prompt, **kw)
tkinter.simpledialog.askstring(title, prompt, **kw)

  The above three functions provide dialogs that prompt the user to enter a value of the desired type.

class tkinter.simpledialog.Dialog(parent, title=None)

  The base class for custom dialogs.

  > body(master)

  >   Override to construct the dialog’s interface and return the widget that should have initial focus.

  > buttonbox()

  >   Default behaviour adds OK and Cancel buttons. Override for custom button layouts.

## `tkinter.filedialog` — File selection dialogs

Source code: Lib/tkinter/filedialog.py

The `tkinter.filedialog` module provides classes and factory functions for creating file/directory selection windows.

### Native Load/Save Dialogs

The following classes and functions provide file dialog windows that combine a native look-and-feel with configuration options to customize behaviour. The following keyword arguments are applicable to the classes and functions listed below:

> parent - the window to place the dialog on top of
> title - the title of the window
> initialdir - the directory that the dialog starts in
> initialfile - the file selected upon opening of the dialog
> filetypes - a sequence of (label, pattern) tuples, ‘*’ wildcard is allowed
> defaultextension - default extension to append to file (save dialogs)
> multiple - when true, selection of multiple items is allowed

Static factory functions

The below functions when called create a modal, native look-and-feel dialog, wait for the user’s selection, then return the selected value(s) or `None` to the caller.

tkinter.filedialog.askopenfile(mode='r', **options)
tkinter.filedialog.askopenfiles(mode='r', **options)

  The above two functions create an `Open` dialog and return the opened file object(s) in read-only mode.

tkinter.filedialog.asksaveasfile(mode='w', **options)

  Create a `SaveAs` dialog and return a file object opened in write-only mode.

tkinter.filedialog.askopenfilename(**options)
tkinter.filedialog.askopenfilenames(**options)

  The above two functions create an `Open` dialog and return the selected filename(s) that correspond to existing file(s).

tkinter.filedialog.asksaveasfilename(**options)

  Create a `SaveAs` dialog and return the selected filename.

tkinter.filedialog.askdirectory(**options)
  Prompt user to select a directory.
  Additional keyword option:
  mustexist - determines if selection must be an existing directory.

class tkinter.filedialog.Open(master=None, **options)
class tkinter.filedialog.SaveAs(master=None, **options)

  The above two classes provide native dialog windows for saving and loading files.

Convenience classes

The below classes are used for creating file/directory windows from scratch. These do not emulate the native look-and-feel of the platform.

class tkinter.filedialog.Directory(master=None, **options)

  Create a dialog prompting the user to select a directory.

Note

The FileDialog class should be subclassed for custom event handling and behaviour.

class tkinter.filedialog.FileDialog(master, title=None)

  Create a basic file selection dialog.

  cancel_command(event=None)

    Trigger the termination of the dialog window.

  dirs_double_event(event)

    Event handler for double-click event on directory.

  dirs_select_event(event)

    Event handler for click event on directory.

  files_double_event(event)

    Event handler for double-click event on file.

  files_select_event(event)

    Event handler for single-click event on file.

  filter_command(event=None)

    Filter the files by directory.

  get_filter()

    Retrieve the file filter currently in use.

  get_selection()

    Retrieve the currently selected item.

  go(dir_or_file=os.curdir, pattern='*', default='', key=None)

    Render dialog and start event loop.

  ok_event(event)

    Exit dialog returning current selection.

  quit(how=None)

    Exit dialog returning filename, if any.

  set_filter(dir, pat)

    Set the file filter.

  set_selection(file)

    Update the current file selection to file.

class tkinter.filedialog.LoadFileDialog(master, title=None)

  A subclass of FileDialog that creates a dialog window for selecting an existing file.

  ok_command()

    Test that a file is provided and that the selection indicates an already existing file.

class tkinter.filedialog.SaveFileDialog(master, title=None)

  A subclass of FileDialog that creates a dialog window for selecting a destination file.

  ok_command()

    Test whether or not the selection points to a valid file that is not a directory. Confirmation is required if an already existing file is selected.

## `tkinter.commondialog` — Dialog window templates

Source code: Lib/tkinter/commondialog.py

The `tkinter.commondialog` module provides the `Dialog` class that is the base class for dialogs defined in other supporting modules.

class tkinter.commondialog.Dialog(master=None, **options)
  show(color=None, **options)

    Render the Dialog window.
